Question

If you are supposed to put in 2/4 a cup sugar for a recipe, can you just put in a half cup of sugar?

Answer 1

I would assume so.

Given $\frac{2}{4}$, we can simplify the fraction to $\frac{1}{2}$

Both would obtain the same proportions, so I don't see why putting a half cup of sugar would make things any different.

Hope this is the answer you are looking for.

Answer 2

Yes. 1/2 and 2/4 are the same fraction equality.
